Energy balance
Subjects consuming 1.75 g·kg−1·d−1 of protein (DEF-HP) lost 0.3 kg less lean mass and 0.4 kg more fat compared to those consuming 1.0 g·kg−1·d−1 (DEF) during a 1000 kcal·d−1 energy deficit.
Higher protein intake during an energy deficit may help preserve lean mass while promoting fat loss.
StrongSupportsmedium confidence
In that period, the seven males in the DEF-HP group, consuming more than twice the RDA for protein, lost 0.3 kg less lean mass and 0.4 kg more fat when placed in a 1000 kcal·d−1 exercise-induced energy deficit.
Why this rating
Based on the controlled study design mentioned in the abstract.
